MULTIPLE HARROW.

Application led September 19, 1912.

T0 all whom it may concern:

Be it known that I, CHARLES E. DEIBLER, a citizen of the United States,residing at Lakeville, in the county of Dakota, State of Minnesota, haveinvented certain new and useful Improvements in Multiple Harrows; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in multipleharrows.

The principal object of the invention is to provide a plurality ofseparably collapsible harrows and a knock down draft bar to and fromwhich said harrows are adapted to be attached and detached, whereby theliarrows may be collapsed and the draft bar knocked down andsuperimposed upon the harrow so as to occupy but little space when notbeing used or when transporting the same.

Another object of the invention is to provide a sectional draft barhaving a plurality of harrows which are so constructed that the sectionsmay be readily assembled or disassembled.

A further object of the invention is to provide a harrow of thecharacter described which is composed of a relatively few number ofparts, is therefore simple in construction and is cheap to manufacture.

Vith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction within the scope ofthe claims may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a top plan view of a complete harrowconstructed in accordance with my invention, Fig. 2 is an end elevationthereof, Fig. 3 is a detail cross sectional view taken on the line 3 3of Fig. 1, Fig. 4 is a detail elevation showing the connection betweenthe abutting ends of the main evener bar sections, Fig. 5 is a detailperspective view showing one of the means for locking the adjacent endsof the main draw bar sections together, Fig. 6 is an enlarged detailview, partly in section, of one Specification of Letters Patent.

of the clevises, Fig. 7 is a plan view of the center harrow sectionshown in its collapsed position, and Fig. 8 is a plan View of one of theend harrow sections, showing the same in its collapsed position.

Like reference numerals designate corresponding parts in all the figuresof the drawings.

Referring to the drawings, A designates a sectional draw bar, and thisbar includes a pair of main sections 5 5 and a front section 6, all ofsaid sections being of substantially the same length. The front sectionG is disposed in advance of the main sections 5 5 and equally overlapsthe inner ends of said main sections. Attached to the rear face of theinner end of one of the main sections 5 is a plate 7, and extendingrearwardly from this plate is a horizontal eye 8. Attached to the rearface of the inner end of the other main section 5 is a plate 9, and thisplate is formed with a vertical eye 10. A hook bolt 11 has its threadedshank disposed within the eye 10 and has its hook 12 engaged with theeye 8. A nut 13 is engaged with the threaded end of the shank andoperates against the eye 10. As a result, upon manipulation of the nut13, the sections 5 5 are drawn tightly together.

In order to detachably secure the main sections 5 5 and the frontsection 6 together, there is provided a pair of U-shaped clamps M l,each clamp being disposed transversely of the sections and arrangedadjacent a respective end of the front section 6. Each clamp comprises apair of spaced arms 15 15 and a connecting portion 16, the latter beingcentrally formed with a threaded opening 17. The connecting portion 16is disposed in spaced relation to the rear face of a respective mainsection 5, and the arms 15 are of such lengths as to extend in advanceof the front section 6, the extreme ends of the arms 15 being formedwith eyes 18 18. A bolt 19 is disposed within the eyes 18 of the arms15, and loosely mounted on this bolt is a grooved roller 20. Connectingthe arms 15 directly in advance of the front section 6 is a verticalbolt 21, and this bolt is seated within a clip 22 carried by the frontsection 6. A vertical bolt 23 extends through an opening formed in arespective main section 5, and this bolt operates in slots 24 24 formedin the arms 15. A wear plate 25 is positioned against the rear face of arespective main section 5 and a tightening screw 26 operates in thethreaded opening 17 and bears against the plate 25. 1t will thus beobserved that upon rotation of the screw 26 in one direction, the clamp14 will be drawn rearwardly, and as a result, the bolt 21 will bepositioned within the clip 22. By means of the clip 22 all swingingmovements of the clamp are prevented.

Secured to the inner end of one main section 5 are forwardly andinwardly inclined upper and lower arms 28-28, the front end of said armsextending in advance of the front section 6 and carrying a bolt 29.Loosely mounted upon this bolt is a grooved roller 30. Extendinginwardly and forwardly from the inner end of the other main section 5 isa pair of spaced upper and lower arms 31-31, the forward ends of saidarms terminating in hooks adapted for engagement with the bolt 29 aboveand below the roller 30. EX- tending forwardly from the outer ends ofthe main sections 5 are hook arms 33-3'3, the forward end of each armextending in an outwardly directed hook A cable 35 operates in rear ofand against the rollers 20-20 and 30, and has its ends provided witheyes 36-36 for engagement with the hooks 34. Rings 37-37 are suitablyconnected to the cable 35 on opposite sides of the pulley 30, and adraft element of any suitable construction (not shown) is adapted to beconnected to these rings. Secured to the main sections 5 and extendingrearwardly therefrom is a plurality of U-clips 38, and to each of theseclips is connected one or more rings 39. Carried by the outer ring 39 isa clevis 40. This clevis is of U- shaped construction and includesspaced arms 41-41 and a connecting portion 42. A coupling pin 43 ismounted in suitable openings formed adjacent the free ends of the arms41, and is formed with a countersunk head 44. A keeper' 45 is pivotallyconnected, as at 46, to the arm 41 which receives the head 44, and thiskeeper is norinally arranged to cover the head and thereby lock the pin43 against accidental displacement.

My invention further comprises a plurality of harrow sections consistingof a center section B and a plurality of outer sections C, all of saidsections being arranged in alinement and in rear of the draft bar A.

The center harrow section B comprises a main bar 47, and a pair of frontand rear transverse spacing arms 48 and 49 are centrally connected tosaid bar intermediate its ends. A pair of forwardly converging side bars50-50 are each pivotally connected adjacent its forward end, as at 51 tothe respective end of the front spacing arm 48. The front end of eachside bar 50 is beveled, as at 52, for engagement with the main bar 47. Apair of forwardly converging inner side bars 53-53 are each pivotallyconnected adjacent its forward end, as at 54, to the respective end ofthe rear spacing arm 49.

The front end of each inner side bar 53 is beveled, as at 55, forengagement with the niain bar 47 centrally of its length. A lever 56which is considerably longer than the front spacing arm 48 is pivotallyconnected, as at 57, centrally of its ends to the main bar 47 in advanceof said arm 48. A pair of outer side bars 58-58 are each pivotallyconnected adjacent its forward end, as at 59, to the adjacent end of thelever 56. A latch bar 60 is pivotally connected at one end to the rearend of the main bar 47 by means of a winged bolt 61. This latch bar isformed with a plurality of inwardly extending slots 62 which are spacedequidistant from each other and are adapted to receive pins 63 that arerespectively carried by the rear ends of the converging side bars 50 and53 and with a winged nut 64 which is carried by the rear end of oneouter side bar 58. A latch bar 65 which is similar in construction tothe latch bar 60 is pivotally connected at one end, as at 66, to therear end of the other side bar 58. rlhe latch bar 65 is likewise formedwith a plurality of inwardly extending slots 67 which are spacedequidistant apart for receiving pins 68 carried by the rear ends of theother inclined bars 50 and 53, and the slot 67 opposite the pivot 66 isadapted to receive the winged bolt 61. As a result of this constructionthe side bars 50, 53 and 58 are held in spaced and forwardly convergingrelations by means of the latch bars 60 and 65.

Each outer harrow section C is formed from a plurality of spacedparallel bars 70. A front link 71 is pivotally connected to the forwardends of the bars by means of pivot bolts 72. A rear link 73 is pivotallyconnected to the rear ends of the bars 70 by means of pivot bolts 74. Abrace 75 is pivotally connected at one end, as at 7 6. to the rear endof one of the outer bars 70 and in advance of the rear link 73. The freeend of this brace is beveled, as at 77, for engagement with the rearedge of the front link 71 at a point diametrically opposite the pivot76. A catch 78 is pivotally connected adjacent the free end of the brace75 and is adapted when the bars are in their operative positions to beengaged with an adjacent bolt 72 and thereby lock the parts of theharrow against collapsing. Harrow teeth 7 9 are carried by each of thebars 70.

Secured to the forward ends of the outer side bars 58 of the centerharrow section B, and to the forward ends of the outer bars 70 of eachharrow section C, are draft bars 80, and each bar is formed with aseries of spaced openings 81. The clevises 40 which are connected to themain sections 5 of the draw bar are connected to the draft bars 80through any one of the openings 81 as Will be readily understood.

From the foregoing, it Will be observed that When it is desired totransport this implement, the harroW sections B and C are firstdisengaged from the sectional draw bar A. These harrovv sections arethen collapsed as shown in Figs. 7 and 8. The draw bar A can then bereadily disassembled and the main sections 5 and the front sections 6together with their attachments can then be readily positioned upon theharrow frames B and C. As a result, When the implement is arranged inthis relation, it Will occupy but very little space.

Vhat is claimed is:

1. In an agricultural implement, a draw bar comprising in combination, apair of main sections arranged end to end, a front section overlappingthe inner ends of the main sections, and means for connecting all ofsaid sections to form a unitary structure, said means comprising a pairof U-shaped clamps which are respectively disposed around the outer endsof the front section and the inner ends of the main sections, a

transverse bolt carried by each clamp and operating against the frontsection, and an adjusting screw carried by each clamp and operatingagainst the respective main section for drawing said clamp tightly tosaid sections.

2. In an agricultral implement, a draw bar comprising in combination, apair of main sections arranged end to end, a. front section overlappingthe inner ends of the main sections, plates respectively secured to therear faces of the inner ends of the main sections, one of said platesbeing bent rearwardly and formed with a threaded opening, an eye carriedby the other plate, a hook bolt having its hook engaged in the eye andhaving its shank engaged in the opening, and a nut engageable with theshank and bearing against the first mentioned plate for locking saidsections against longitudinal movement, and means connecting the mainand front sections for preventing lateral movement therebetween.

In testimony whereof, I aix my signature, in presence of two Witnesses.
